Abstract
The invention relates to a bottom control type sample filtering container consisting of a sealing plug, a cup cover, a cup body, a piston rod, a piston, a clutch spring, a drainage needle and a bottom cover. The piston rod is arranged in an intermediate hole at the bottom of the cup body, the piston is tightly sleeved on the bulge of the piston rod, the drainage needle is connected and fixed at the lower end of the piston rod through a screw thread, one end of the clutch spring is connected with the bottom of the cup body, and the other end is connected with a drainage needle flange. The bottom control type sample filtering container is characterized by being also provided with a double-layer filter system consisting of a first layer of filter screen and a second layer of filter screen, and the shaft of the first layer of filter screen penetrates through the intermediate hole of the second layer of filter screen and is fixed in the top hole of the piston rod. The invention has the advantages that sanitation is ensured, the sealing is good, and liquid in the container can be filtered in several times as required.
Description
Technical field
The present invention relates to a kind of filter, be meant a kind of bottom control type sample filtering container specifically.
Background technology
In fields such as medical test, Bioexperiment, need filtering container that getting liquid sample such as ight soil, urine, river etc. are filtered.Existing filtering container is such as " disposable feces concentrate container " (as Fig. 1, Fig. 2).As Fig. 1, take manually to remove container top lock 1 back and manually stab and open container inner bottom part center hole and make liquid be downward through the bottom screen pack; Or as Fig. 2, in the container side utilization mode that pulls flame-arrester vent plug 2 is drawn back, centre bore is opened allowed liquid flow down.Its shortcoming is: can only manually control by top lock or side flame-arrester vent plug, and can only open and can not close, can not the controlled filter amount, and all liq in can only the intact container of disposable filtering.
Summary of the invention
The invention provides the bottom control type sample filtering container that the liquid in a kind of container can gradation filters.
The present invention adopts following technical scheme: bottom control type sample filtering container, by sealing-plug, bowl cover, cup, piston rod, piston, the clutch spring, drainage needle, bottom constitutes, piston rod places in the interstitial hole of bottom of cup, piston tightly is enclosed within on the projection of piston rod, drainage needle is fixed on piston-rod lower end by being threaded, clutch spring one end is connected with bottom of cup, the other end links to each other with the drainage needle flange, it is characterized in that: also be provided with the double medium filtration system that ground floor screen pack and second layer screen pack are formed, the axle of ground floor screen pack passes second layer screen pack interstitial hole and is fixed in the piston rod topped hole.
Bottom control type sample filtering container can also be provided with sampler, and sampler is installed in the bowl cover designation hole.
The solution that by sampler needs the is filtered during use filtering container of packing into need not airtightly can not add sealing-plug.If solid sample (as stool sample) needs close dissolving to filter, use sampler that it is put into seal cap behind the container, sting the soft hole of reservation in the middle of the capping with the device of syringe-like, the liquid injecting container of dissolved solid sample.Then bottom is taken off, test tube or other receiving vessels are placed into below the drainage needle, the promotion drainage needle moves up, drainage needle compression clutch spring promotes piston rod drive piston, the ground floor screen pack moves up, when on move on also under the promotion of second layer screen pack at piston when moving certain displacement, form certain space in the middle of ground floor screen pack and the second layer screen pack this moment, play the effect of double medium filtration, move in the continuation in container sample by cup at the bottom of the gap of upper surface and piston lower surface flow down, flow out by drainage needle.When stopping, unclamping drainage needle, the clutch spring is return original position with drainage needle, and piston blocks up the gap, has promptly controlled sample and has outwards flowed out.The present invention has health, closure is good, and the liquid in the container is the advantage of gradation filtration as required.

Fig. 1, Fig. 2 are existing disposable feces concentrate container structural representation.
Fig. 3 is a schematic appearance of the present invention.
Fig. 4 is a structural representation of the present invention.
Fig. 5 filters view for the present invention.
The specific embodiment
Describe the specific embodiment of the present invention in detail below with reference to Fig. 3, Fig. 4, Fig. 5.
Bottom control type sample filtering container, by sealing-plug 1, bowl cover 2, cup 3, piston rod 5, piston 6, clutch spring 7, drainage needle 8, bottom 9 constitutes, piston rod 5 places in the interstitial hole 12 of bottom of cup, piston 6 tightly is enclosed within on the projection of piston rod 5, drainage needle 8 is fixed on piston rod 5 lower ends by being threaded, clutch spring 7 one ends are connected with bottom of cup, the other end links to each other with the drainage needle flange, also be provided with the double medium filtration system that ground floor screen pack 4 and second layer screen pack 11 are formed, the axle of ground floor screen pack 4 passes second layer screen pack 11 interstitial holes and is fixed in piston rod 5 topped hole.
Bottom control type sample filtering container also is provided with sampler 10, and sampler 10 is installed in bowl cover 2 designation holes.
The solution that by sampler 10 needs the is filtered during use filtering container of packing into need not airtightly can not add sealing-plug 1.If solid sample (as stool sample) needs close dissolving to filter, after putting into container with it, use sampler 10 adds sealing-plug 1, sting the soft hole of sealing-plug 1 middle reservation with the device of syringe-like, the liquid injecting container of dissolved solid sample.Then bottom 9 is taken off, test tube or other receiving vessels are placed into below the drainage needle 8, promoting drainage needle 8 moves up, drainage needle 8 compression clutch springs 7 promote piston rod 5 drive pistons 6, ground floor screen pack 4 moves up, when on when moving certain displacement second layer screen pack 11 moving on also under the promotion of piston 6, form certain space in the middle of ground floor screen pack 4 and the second layer screen pack 11 this moment, play the effect of double medium filtration, move in the continuation in container sample by cup at the bottom of the gap of upper surface and piston 6 lower surfaces flow down, flow out by drainage needle 8.When stopping, unclamping drainage needle 8, clutch spring 7 is return original position with drainage needle 8, and piston 6 blocks up the gap, has promptly controlled sample and has outwards flowed out.The present invention has health, closure is good, and the liquid in the container is the advantage of gradation filtration as required.
Above-mentioned is a specific embodiment of the present invention, but design concept of the present invention is not limited thereto, and allly utilizes this design that the present invention is carried out the change of unsubstantiality, all belongs to the behavior of invading protection domain of the present invention.
